Section 4: Troubleshooting

4.5.5 The Display is Jittery or Unstable

Check the following:
• If the image display is jittery or blinking erratically, ensure the source is properly connected and of adequate
quality for detection. With a poor quality or improperly connected source, the projector will repeatedly
attempt to display an image, however briefly.
• The horizontal or vertical scan frequency of the input signal may be out of range for the projector.
• The sync signal may be inadequate. Correct the source problem.

4.5.6 The Display is Faint

Check the following:
1. The source may be double terminated. Ensure the source is terminated only once.
2. The source (if non-video) may need sync tip clamping.

4.5.7 The Upper Portion of the Display is Waving, Tearing or Jittering

This can occur with video or VCR sources. Check your source.

4.5.8 Portions of the Display are Cut OFF or Warped to the Opposite edge

Resizing may need adjustment. Adjust until entire image is visible and centered.

4.5.9 Display Appears Compressed (Vertically Stretched)

Check the following:
• The frequency of the pixel sampling clock is incorrect for the current source.
• Sizing and positioning options may be adjusted poorly for the incoming source signal.
• Use an anamorphic lens for typical HDTV and anamorphic DVD sources that have been re-sized and
vertically stretched, via 3rd-party software.

4.5.10Data is Cropped from Edges

To display the missing material, reduce image size to fill the display area available in the projector, then stretch
vertically to fill the screen from top to bottom. Add the anamorphic lens to regain image width, if required.

4.5.11Display Quality Appears to Drift from Good to Bad, Bad to Good

Check the following:
• The source input signal may be of low quality.
• The H or V frequency of the input may have changed at the source end.

4.5.12Display has Suddenly Froze

If the screen blacks out inexplicably, it is possible excessive voltage noise on the AC or ground input has
interrupted the projector's ability to lock on to a signal. Power down and up again.
